Full superconducting gap and type-I to type-II superconductivity transition in single crystalline NbGe2

Dongting Zhang, Tian Le, Baijing Lv +7

We report a mechanical point-contact spectroscopy study on the single crystalline NbGe${}_2$ with a superconducting transition temperature $T{}_{\mathrm{c}}$ = 2.0 - 2.1 K. The differential co…
